Option C:

\left(\begin{array}{cc}-6 & 0 \\12 & 21\end{array}\right)

Solution:

Given data:

3\left[\begin{array}{cc}-2 & 0 \\4 & 7\end{array}\right]

To find the product:

Scalar element = 3

<u>Scalar multiplication:</u>

<em>Multiply each of the matrix element by a scalar.</em>

Here multiply each of the matrix element by 3.

3\left(\begin{array}{cc}-2 & 0 \\4 & 7\end{array}\right)=\left(\begin{array}{ccc}3(-2) & 3 \cdot 0 \\3 \cdot 4 & 3 \cdot 7\end{array}\right)

Simplifying each element, we get

                     =\left(\begin{array}{cc}-6 & 0 \\12 & 21\end{array}\right)

The value of the given matrix is \left(\begin{array}{cc}-6 & 0 \\12 & 21\end{array}\right).

Option C is the correct answer.

Answer:

  3.  m∠A < 80°

Step-by-step explanation:

The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.

If we assume that angle measures cannot be zero, then we must have ...

  m∠A +m∠N = 80°

  m∠A = 80° -m∠N

Since m∠N > 0, the measure of angle A must be less than 80°.

This conclusion matches choice 3.
